The principles and practice of dental surgery. ion,(see Fig. 278, in which the artist has represented the holes en-tirely too small,) a coating of varnish is applied to every part exceptthat which is to be covered by the base for the artificial part is now covered with a plate of thick tin foil, stiffenedby the application of a sheet of soft wax to the part within thearch. This may be a quarter or three-eighths of an inch thick,and when it has hardened, a rim of softened wax is placed alongthe alveolar border and trimmed down with a knife until itswidth is a little greater than the length required for the artificialteeth. Remove this and the stiffened tin foil plate together,place them in the mouth before tiie wax hardens, and if the rimis of the right width all round, request the patient to bite uponit. closing tlie lower jaw naturally, until a distinct imprint of all 786 CHEOPLASTIC PROCESS. the lower teeth is made in it, (See Fig. 278.) This done, thewax and plate are removed from the mouth, replaced on the Fig. model, and the lower half-model made in the manner describedin a preceding chapter. After the lower half-model, the wax and tin foil have beenremoved, the portion of the model representing the alveolarridge and roof of the mouth, is covered with a fresh plate of is accurately moulded to the various depressions and prom-inences with the finger, and with hard rolls of chamois leather, cutnearly to a point at each end, called stumps, (Fig. 279,) such as Fig. 279.
